Abstract
Description
본 발명은 콘크리트, 시멘트, 몰탈, 석고 보드 및 각종 판넬 등의 건축물 및/또는 구조물 내부 마감 부위에 적용되는 무광의 수성 도료 조성물에 관한 것이다. The present invention relates to a matte water-based paint composition applied to the interior finishing parts of buildings and/or structures such as concrete, cement, mortar, gypsum board, and various panels.
일반적으로 콘크리트, 시멘트, 몰탈, 석고 보드 및 각종 판넬 등 건축물 및/또는 구조물 내부 마감 부위에의 도장은 재료의 보호를 목적으로 시작되어, 열화 방지, 물성 향상, 경관 증진 및 시공의 편의성을 위한 것으로 그 활용이 증가되고 있다.In general, painting of concrete, cement, mortar, gypsum board, and various panels, etc., is started for the purpose of protecting materials, and is intended to prevent deterioration, improve physical properties, enhance scenery, and facilitate construction. Its use is increasing.
한편, 환경과 보건 등에 관심이 높아짐에 따라 건축물 내장용 도료 분야에서도 환경적 요구가 높아지고 있다. 친환경 건축 재료 사용에 대한 요구에 따라, 건축물 등의 내장용 도료에 있어서 수성 도료를 이용한 마감 시공이 꾸준히 증가하고 있다. On the other hand, as interest in the environment and health increases, environmental demands are also increasing in the field of interior paints for buildings. In accordance with the demand for the use of eco-friendly building materials, the use of water-based paints for interior paints for buildings is steadily increasing.
그러나, 종래 건축물 내장용 수성 도료는 유성 도료와 달리 도막 강도가 약하고 접착력이 부족하여 스크래치 등의 물리적 힘에 의하여 도막이 손상되는 버니쉬(Burnish) 현상 또는 도막의 탈락이 발생되는 문제가 있으며, 특히, 외부 오염성에 취약하고 피착된 오염물을 쉽게 제거하기 어려운 문제가 있다. However, unlike oil-based paints, conventional water-based paints for building interiors have a problem in that the paint film strength is weak and adhesion is insufficient, so that the paint film is damaged by physical forces such as scratches or the paint film is detached. There is a problem in that it is vulnerable to contamination and it is difficult to easily remove the adhered contaminants.
또한, 다양한 유형의 건물에 대한 인테리어적 요구 사항을 충족시키기 위해 무광의 도료가 사용되고 있으나, 일반적으로 무광의 수성 도료는 유성 도료와 달리 도막 강도 및 스크래치에 대한 내성이 약하고 접착력이 부족하여 내구성에 취약할 수밖에 없다.In addition, matte paints are used to meet the interior requirements of various types of buildings, but generally, unlike oil-based paints, matte water-based paints have poor film strength and resistance to scratches, and lack of adhesive strength, making them vulnerable to durability. Have no choice but to.
본 발명의 목적은, 탁월한 내후성 및 내구성을 가지고, 흠집이나 스크래치 방지 효과가 뛰어나며, 오염물의 제거가 용이한 무광의 수성 도료 조성물을 제공하는 것이다. An object of the present invention is to provide a matte water-based coating composition that has excellent weather resistance and durability, is excellent in preventing scratches and scratches, and is easy to remove contaminants.
본 발명의 다른 목적은 친환경적이고, 항균 성능 및 곰팡이 억제 기능이 우수한 무광의 수성 도료 조성물을 제공하는 것이다. Another object of the present invention is to provide a matte water-based paint composition that is environmentally friendly and has excellent antibacterial and antifungal properties.
본 발명의 또 다른 목적은 상기 수성 도료 조성물을 함유하는 친환경 건축물 내부용 도료를 제공하는 것이다. Another object of the present invention is to provide a paint for the interior of an eco-friendly building containing the above water-based paint composition.

마찰견뢰도 시험기(crockmeter, SDL Atlas 사)를 사용하여 DIN EN ISO 105-X12:2002-12에 따라 9 μm, 15 μm 281Q 사포를 사용하여 10회 이중 마찰 및 9 N 힘의 적용을 수행하고 후속적으로 60°및 85°에서 잔여 광택을 결정함으로써 결정되었다. 상기 9 μm, 15 μm는 사포, 즉, 샌드페이퍼 표면의 입자 크기를 나타내며 입도가 클수록 표면이 거친 것을 나타낸다. 본 시험에서는 사포로 표면 마찰을 가하여 시험 전과 후의 광택 변화를 측정하였으며, 광택 변화가 적을수록 스크래치 저항성이 우수하다. 상기 60° 및 85°의 각도는 빛이 조사되는 각도를 나타내며 센서로 들어오는 빛의 양으로 광택의 높고 낮음이 측정된다. According to DIN EN ISO 105-X12:2002-12 using a rubbing fastness tester (crockmeter, SDL Atlas) 10 times of double rubbing and application of 9 N force using 9 μm and 15 μm 281Q sandpaper, followed by It was determined by determining the residual gloss at 60° and 85° with . The 9 μm and 15 μm indicate the particle size of the surface of the sandpaper, that is, the sandpaper, and the larger the particle size, the rougher the surface. In this test, surface friction was applied with sandpaper to measure gloss change before and after the test. The smaller the gloss change, the better the scratch resistance. The angles of 60° and 85° represent angles at which light is irradiated, and high and low gloss is measured by the amount of light entering the sensor.
결과를 도 2에 나타낸다. 도 2로부터 알 수 있듯이, 실시예 1의 도료 조성물은 스트레스 이전, 9 μm, 15 μm 스트레스 처리 후의 값이 거의 동등하게 나타나 광택 변화가 거의 없고 스크래치 저항성이 우수한 것으로 나타났다. 비교예 1, 2의 경우, 표면 마찰 시험 전후 값에 차이가 커서 스크래치 저항성이 떨어지는 것이었으며, 비교예 1의 경우 특히 85° 조건에서 스크래치 저항성이 현저히 떨어지는 것이었다. Results are shown in FIG. 2 . As can be seen from FIG. 2, the paint composition of Example 1 showed almost the same values before stress, after 9 μm and 15 μm stress treatment, showing little change in gloss and excellent scratch resistance. In the case of Comparative Examples 1 and 2, the difference between the values before and after the surface friction test was large, and the scratch resistance was poor.

사트라 마찰 시험기 (Satra rub tester)를 사용하여 2.5KG의 하중을 받는 펠트 패드 아래에 시편을 설치한 후 500, 1000, 2000, 4000 사이클 시험을 실시하고, Satra 시험방법에 의하여 외관을 평가하였다. 결과를 표 5에 나타낸다.After installing the specimen under the felt pad under the load of 2.5KG using a Satra rub tester, 500, 1000, 2000, and 4000 cycle tests were performed, and the appearance was evaluated by the Satra test method. The results are shown in Table 5.
표면 변화가 적을수록 내스크래치성이 우수하다. The smaller the surface change, the better the scratch resistance.
표 5에 나타난 바와 같이, 실시예 1은 4000 사이클 이후에도 표면 변화가 거의 없는 것으로 나타나 내구성 및 내스크래치성이 매우 우수한 것으로 나타났다. 비교예 1 내지 2의 경우, 500 사이클 이후 표면이 매우 빛나거나 문질러져 결과를 확인할 수 없는 것이었다. As shown in Table 5, Example 1 showed almost no surface change even after 4000 cycles, showing very excellent durability and scratch resistance. In the case of Comparative Examples 1 and 2, the surface was very shiny or rubbed after 500 cycles, so the results could not be confirmed.
마. 습윤 스크럽 저항(Wet scrub resistance)mind. Wet scrub resistance
Wet Abrasion scrub Tester (BYK Instrument 사)를 이용하여 Nylon brush(ASTM 2486)와 Real hair bristles(DIN 53778/B4)의 2가지 타입 브러쉬로 시험편을 각 2000회 문지른 후의 시편에서의 시험 전후 광택 변화를 확인하였다. 결과를 표 6(Nylon brush), 표 7(Real hair bristles)에 각각 나타낸다.Wet Abrasion scrub Tester (BYK Instrument Co.) was used to scrub the test piece 2000 times each with two types of brushes, nylon brush (ASTM 2486) and real hair bristles (DIN 53778/B4), and then check the change in gloss before and after the test. did The results are shown in Table 6 (Nylon brush) and Table 7 (Real hair bristles), respectively.
표 6, 7에 나타난 바와 같이, 실시예 1의 도료 조성물은 스크럽 처리 전후의 광택 변화가 거의 없는 것이었다. 이에 대해, 비교예 1, 2의 경우 스크럽 스트레스 처리 전후의 광택변화가 심한 것으로 나타났으며 내스크래치성이 떨어지는 것이었다. As shown in Tables 6 and 7, the coating composition of Example 1 showed little change in gloss before and after scrub treatment. On the other hand, in the case of Comparative Examples 1 and 2, it was found that the gloss change before and after the scrub stress treatment was severe, and the scratch resistance was poor.
